Guidewire Pushing Force Tester

The Guidewire Pushing Force Tester is a testing device used to verify and record the performance characteristics of interventional medical devices (including balloon catheters, guidewires, and stent delivery systems). This system simulates the tracking force and pushing efficiency of the product within human blood vessels. It offers a variety of test combinations, and the test results can be used for routine data analysis and product performance evaluation.

Applications

The guidewire pushing force tester is a precision testing tool in the medical device industry, mainly used to test the mechanical properties of guidewires during the pushing process. This equipment plays a crucial role in the research, development, production, and quality - control processes of medical devices.

Its specific uses include: Testing in the R & D Stage: In the R & D stage of medical devices, the guidewire pushing force tester helps R & D personnel conduct comprehensive tests on the performance of new guidewires. By simulating pushing operations under different conditions, testers can obtain data on the mechanical properties of guidewires in various scenarios, and thus evaluate whether they meet the design requirements. This data provides valuable references for R & D personnel, enabling them to optimize the structure and performance of guidewires, and improve the overall quality of medical devices.

Quality Control in the Production Stage: During the production stage, the application of the guidewire pushing force tester ensures that each batch of guidewires meets the quality requirements. By regularly testing guidewires in the production process, manufacturers can promptly identify and resolve potential quality issues, ensuring product consistency and stability.

Optimization of Process Parameters: The guidewire pushing force tester can also be used to optimize process parameters during production, aiming to increase production efficiency and reduce costs.

Competitive Product Analysis and Market Strategy Formulation: Through strict testing of finished guidewires, manufacturers can ensure that products meet the predetermined performance standards. Meanwhile, this equipment can also be used to analyze and compare competing products on the market, helping manufacturers understand their own advantages and disadvantages, and thus formulate more targeted market strategies.

Comprehensive Testing Tasks: The guidewire pushing force tester can also be integrated with other medical equipment to perform more complex testing tasks. For example, by connecting it with a blood vessel simulator, testers can simulate the pushing process of guidewires in real blood vessels, and thus evaluate their performance more accurately. This comprehensive testing method contributes to improving the precision and reliability of medical device research and production.

Test Procedures

1. Before testing, appropriate test conditions, such as water flow rate and pressure, should be set according to the pipe specifications and testing requirements. This helps to ensure the accuracy and reliability of the measurement results.

2. When connecting the pipes, ensure a tight, leak-free connection. Any leaks will affect the accuracy of the measurement results.

3. During the testing process, keep the testing instrument and pipes clean to avoid contamination affecting the test results. Regularly clean and maintain the instrument to ensure its proper functioning and extend its service life.

4. After the test is completed, turn off the testing instrument, disconnect the pipes, and clean and dry them for future use. This helps prevent corrosion and damage to the instrument and pipes due to prolonged disuse.
